The most romantic city in the world, Paris is a global center for art, fashion, gastronomy, and culture. Paris returns to tranquillity in the autumn and when winter and the holidays arrive, Paris' streets are illuminated, revealing the city's magic. On a beautiful day, a stroll along the Seine's banks is a sight to behold: grand historical buildings reflected in its waters, classic Parisian roofs, and the Seine's bridges, each with its distinct style. Pei's pyramid surrounded by the Louvre's classic courtyard or the Musée du Quai Branly at the foot of the Eiffel Tower is just a few examples of architectural contrasts that only add to the city's splendor.
